Application filed July 7, 1885. Serial No. l70,S5l. (Nomodel.)

To all 'whom it may concern:

Be it known that l, HERMANN WILD, of Brooklyn, county of Kings, andState of New York, have invented certain new and useful ImprovementsinBakers Ovens, of which the following is a speciiication.

This invention relates to a bakers oven with two separate furnaces andheating-dues, whereby the oven is kept at uniform heat at a considerablesaving of fuel.;J

In the accompanying drawings, Figure l represents a front elevation ofmy improved bakers oven. Fig. 2 is a horizontal section of the same online x x, Fig. 1;'Fig. 3, a vertical longitudinal section on line y y,Fig. l; Fig. 4, a horizontal section on line e z, Fig. 8; Fig. 5, avertical transverse section through the baking-chamber; and Fig. 6 is ahorizontal section on line c c, Fig. 3.

Similar letters of reference indicate corresponding` parts.

Referring to the drawings, A represents the bakingchamber that graduallyincreases in width from the front opening toward the side walls, andwhich is lined with lire-bricks in the usual manner. rlhe bottom of thebakingchamber A is formed with tiles of iire-clay, which are laid on abed of sand that is supported by lire-bricks having overlapping edges.rlhe bottom of the baking-chamber is made sloping toward the frontopening, and is heated by means of two separate furnaces, B B, and bytwo systems of heating-dues, C C, by which the baking-chamber can bequickly heated and kept at a uniform heat. The gratos of thc furnaces BB are set back from the front doors, B B', and provided with separatefire-doors b, between which and the front doors spaces b are arranged,that communicate by vertical Ilucs I)L b'L in the front brick wall witha transverse top flue, C, leading to the chimney. rilhe ilues Ifventilate the spaces in front of the grates and their ashpits and carryoff the heated air. and dust, so as to give less trouble to the handsrunning the oven.

The longitudinal ilues C C run back from the furnaces toward the rearwall of the baking-chamber A, and communicate by vertical, rear lines,O', with longitudinal return-fines O2, which are located in the crown ofthe baking-chamber, and supported by double T- beams that rest on atransverse iron plate, d', at the front part of the baking-chamber, andon the transverse rear wall of the same, as shown in Fig. 3.

The return-lines Cl C2 are formed of top and'bottom tiles of fire-brick,which rest, respectively, on the bases and tops of the double T-beams,and of vertical side-bricks, which cover the webs of the beams, as shownin Fig. 5. The return-lines C2 C2 form with the beams and tilesdescribed the crown of the baking-chamber and heat the-upper part of thesame.

rlhe crown of the baking-chamber A is provided in its rear part with acentral opening, e, that communicates by a central flue, e', with thetransverse top-line, C. The opening c is closed by a sliding damper, E,the damper-rod Eof which passes through the front wall ofthe oven, andhas a handle at its outer end, so as to be conveniently operated foradmitting the escape of steam and heated air from Ythe baking-chamberthrough the ilue c to the chimney, and relieving the baking-chamber fromundue steam-pressure. The return-fines CIl CZ are open at their frontends and connected by two short vertical lues, O, with a second lateralilue, C5, which communicates with the chimney. The vertical ilues O areprovided with horizontal dampers F-and damper-rods F', which extendthrough the front wall and are operated from the front of the oven. Byclosing the dampers F F the iiregases do 'not pass through the returnflues C2 O2, but through a central and side top flue, G, directly to thetransverse front Hue, C5, as shown in dott-ed lines in Figs. 3 and 6.The dampers F are closed when the iire is started in the furnaces andalso when the oven is thoroughly heated, so that the heat of the same isthereby regulated to the proper degree of temperature. A layer, f, ofasbestus, eX- tends over the bricks that cover the returnilues C2 to therear part of the structure, also a second layer, f, vertically throughthe rear wall of the baking-chamber, which layers serve to conline theheat in the baking-chamber and prevent the radiation of the same throughthe top and rear brick walls.

Having thus described my invention, I In testimony that I claim theforegoing as claim as new and desire to secure by Letters my invention Ihave signed my name in pres Patentence of two subscribing witnesses.
